St Benedict's College is a secondary school in Randalstown, County Antrim, Northern Ireland. It is an 11-16 Catholic, all-ability, co-educational college which mainly serves families from the parishes of Randalstown and Antrim.
The college was formed from the amalgamation of St Malachy's High School, Antrim, and St Olcan's High School in Randalstown, a decision agreed upon in March 2006. The newly combined school was renamed St Benedict's College. St Malachy's High School was subsequently demolished, and a rebuilding programme began on the St Olcan's site to develop new facilities.
